Help - Preparation of horseshoe carb specimen

[AKIM at ARSERRC.GOV]

Hi.
I need help to prepare horseshoe crab specimen.  My son had a horseshoe crab
as a pet at home and it has been dead since last Monday.  He want to keep
that in a bottle with alcohol.  But, I am not sure what percentage of alcohol
should be used and what kind of alcohol (ethyl alcohol or isopropyl alcohol etc.)
Any help can be appreciated.

	Thank you.
